Could you tun the following and post the output?

which python
jupyter kernelspec list --json

[cailmdaley]

I found the issue--my python build was corrupted. Thanks!

Hi,
I am facing a similar error in Spyder IDE for Python. I am trying to access it with Python 27. Can you please give me a solution?

[cailmdaley]

In my case, I think this error was caused by something in the OS X distribution of Python ("/Library/Frameworks/Python..."). I solved this by installing a fresh Python build with Homebrew, and setting it to my default Python. Hope this helps!

I encountered a similar problem. pip install --upgrade pyzmq did the trick for me
